Late Winter, Spring
Big Toothed Aspen is one of the last trees to leaf out in the spring. The most abundant and widespread tree in Minnesota is the aspen; a fast growing pioneer tree species. After a clear cut or a fire, Aspen will often be the first tree to grow back. Aspen catkins are an important spring(April)food for black bears delivering approximately 14% protein. Aspen leaves are eaten by black bears in May when trees start leafing out.
